Whose red fruit is more reflective of teaching?In the " Three-Body Problem " series of novels, the red fruit was described as a plant with strong adaptability and high intelligence, able to survive and reproduce in different environments. Therefore, the reflection of whose red fruits are more can be understood as the reflection of " whose fruits are more ".
In the novel, the wisdom and behavior of the red fruit plant were described as very magical and awe-inspiring. In the face of the Three-Body Civilization's attacks and threats, the Red-Fruit Plants had shown strong adaptability and survivability. Not only did they survive in extreme environments, but they also gradually developed and became an important threat to the Three-Body Civilization through wisdom and technological means.
From this point of view, teaching reflection can reflect on how to cultivate students 'creativity and adaptability so that they can maintain a calm, positive and aggressive attitude in the face of various challenges and difficulties. At the same time, it could also reflect on how the education workers paid attention to and valued the individual differences and variety of students and how to guide students to learn and explore independently.
The question of " whose red fruits are more " was not only a plot in a novel, but also reflected people's thinking and discussion about wisdom, adaptability, and individual differences.

2. Demonstrating method: Demonstrate the sticking process and effect of the glass reflective insulation sticker through real objects or videos.
3. Experimental method: organize students to carry out simple experiments to explore the thermal insulation and reflective properties of the glass reflective insulation paste.
4. Group cooperative learning method: Arrange students to discuss, experiment and operate in groups to cultivate students 'cooperation ability and team spirit.
* * 4. Teaching preparation **
1. teaching materials
- Glass reflective thermal insulation paste.
- Different types of glass samples (such as ordinary glass, double glass, etc.).
- Scissors, rulers, rags, and other tools.
- Create a multi-media class, including pictures, videos, principle animations, and other information about the glass reflective insulation paste.
2. [Teaching venue: classroom or laboratory (equipped with operating space and basic equipment for sticking reflective glass insulation tape).]
* * 5. Teaching process **
1. Introduction to a new lesson (5 minutes)
- By showing some photos of buildings or indoor temperature comparison data before and after the use of glass reflective insulation, it attracted the attention of the students and asked,"Why do these buildings have such changes after using a certain material?" This led to the main topic of this lesson--
2. Knowledge explanation (10 minutes)
- This paper introduced the definition, structure and main components of glass reflective insulation paste with the help of a multi-media class.
- Explain in detail the thermal insulation principle of the glass reflective thermal insulation sticker (such as reflecting heat, preventing heat transmission, etc.) and the reflective principle (reflecting light).
- Illustrate the application of glass reflective thermal insulation in construction, agriculture, cars and other fields, so that students can understand its wide range of uses.
3. Demonstrate (10 minutes)
- Take out a glass sample and glass reflective insulation tape and show the students the tools needed (scissors, ruler, etc.).
- While demonstrating, he explained the steps of sticking the glass reflective insulation tape:
- Clean the surface of the glass to ensure that there is no dust, stains, and other impurities.
- According to the size of the glass, cut the appropriate size of the thermal insulation paste, pay attention to leaving a certain edge.
- Starting from one end of the thermal insulation paste, he slowly removed the back glue paper, and at the same time, stuck the thermal insulation paste on the glass. He used a rag or scraper to gently scrape it from the middle to both sides to eliminate air bubbles.
- Check the thermal insulation paste that has been pasted. If there are any upturned or air bubbles, deal with them in time.
4. Group Experiment (20 minutes)
- The students were divided into several groups (3 - 5 people in each group), and each group was given a glass sample, glass reflective insulation paste, tools and other materials.
- The students were asked to follow the steps of the demonstration. The teacher patrolled between the groups and gave timely guidance and help.
- After each group was done, they organized the students to carry out a simple experiment:
- Use a thermometer to measure the surface temperature of the glass before and after the thermal insulation paste (you can use a table lamp to simulate sunlight), record the data, and compare and analyze it.
- Observe the reflective effect of the glass reflective insulation sticker and compare the reflection under different angles.
5. Group discussion and report (10 minutes)
- The groups discussed the results of the experiment and considered the following questions:
- Is the thermal insulation and reflective effect of the glass reflective thermal insulation paste obvious?
- What problems did he encounter during the paste process? How was it resolved?
- According to the experimental results, what do you think are the advantages and limitations of the glass reflective thermal insulation paste in practical applications?
- Each group elected a representative to report and share the results of the group's discussion and experimental experience.
6. Class summary (5 minutes)
- The teacher summarized the content of this lesson, emphasizing the principle, function, sticking points, and discoveries in the experiment of the glass reflective insulation paste.
- Review the students 'performance in experiments and discussions, and give affirmation and encouragement to the students' active participation and innovative thinking.
7. Homework (after class)
- Students were asked to observe their windows or car windows when they got home. If they didn't use the glass reflective insulation tape, they could think about what changes would happen if they used it. If they had already used it, they could further understand the brand, performance, and other information, and write a short essay to describe it.
- Students were encouraged to look up information on new glass insulation or reflective materials on the market and share them in the next class.

Reflective vest, what color is reflective?Common colors such as neon yellow, neon orange, and neon green were more common in reflective vests and had better reflective effects. The fluorescent color could provide a good visual effect in a dark environment, allowing the user to have a good safety warning in case of bad weather or poor lighting, reminding the driver or other personnel to avoid accidents. However, in forests or areas with greenery, neon green may not be the best choice because it may mix with the background color and reduce visibility. In this case, neon yellow or orange may be better.
